[. . . ] Do not make any alterations to the connections of your system with the M60C AC power switched on. To get going: · Use the audio cable supplied to connect the unbalanced input of the speaker to an appropriate preamplifier or surround sound decoder. Switch on the M60C with the switch located next to the AC power inlet. A green light should appear at the front of the unit and you should be able to play music. · · · If you cannot hear any sound, refer to Help! Installing your M60C This section explains how to get the best from your M60C installation. [. . . ] In a custom cabinet it is entirely the responsibility of you and your dealer to ensure adequate ventilation. If in doubt this can determined by operating the unit and monitoring the temperature of the backplate which is also the heatsink. Permanent wiring to a building is prohibited by most building codes. · 1 Preferably within 1 foot, 30cm. M60C User Guide 5 As a Left ­ Right or a Surround pair The locations chosen for a pair of M60Cs are crucial to getting the best possible acoustic result. For two-channel stereo, the two speakers should ideally be equidistant from the main listening position, and the same distance apart. Since it has a horizontal format, the M60C can be mounted on a strong shelf or on a suitable stand ­ about which your dealer can advise. General guidelines In order to get the best acoustic performance from your M60C in your room, you should try to achieve the following: · If possible, have the most acoustically absorbent wall in the room behind the front speakers. They could, for example, be in front of an open bookcase or curtained window, or on each side of a bow window. · If possible, locate the listening position so that your head is at least 60cm from the wall behind you (unless this is acoustically absorbent). Consider the following practical points: · If possible, you should locate the M60C so that the electronics (back) of the speaker are not subjected to long-term strong sunshine. The back plates should be cool (less than hand-hot) when the unit is not in use. · You should not, if possible, locate a M60C with its back to any heat source ­ for example, a central heating radiator. · You should not, locate a M60C with its back fully enclosed so that it cannot dissipate heat from the rear-panel heatsink. Final adjustments The best sound possible will only be obtained if the M60C is firmly mounted and cannot rock. Operation Normally the M60C should be left switched on, even when the unit is not in use. The sound quality of the unit is at its best when the temperature of the components has reached normal working levels. The electronics in the M60C use the very latest techniques to ensure that the idle power consumption of the unit is very low. All audio equipment should be switched off if you expect to be away from the installation for an extended period. M60C User Guide 6 Maintenance There are no user serviceable parts inside the M60C. One or two days after installation check the tightness of the fixing screws of the loudspeaker drivers. These screws may loosen slightly in shipping or with extremes of temperature or humidity, and the speaker will not sound at its best with them loose. It is worth checking these screws after transit or extended periods of loud playing.
